Abstract

L'invention concerne un procédé, un dispositif et un système permettant de déterminer la taille de l'étape de régulation de puissance de transmission de liaison descendante à la fois pour les commandes de régulation de puissance (TPC) de transmission UP et DOWN. Lesdits procédé, dispositif et système utilisent une qualité de réception et une pluralité de seuils pour déterminer les tailles d'étape. L'invention consiste à déterminer la taille de l'étape et les valeurs de commande TPC lorsque la commande TPC est erronée et lorsque la qualité de réception est inférieure à une valeur seuil minimum.
